차세대 지능망은 기존망으로부터 출발하여 끊임없이 진화하는 것으로 새로운 서비스이 도입이 용이한 서비스 독립적인 구조를 가진다. 이러한 차세대 지능망의 구성요소 중 기존 지능망과 차별화시켜 주는 구성요소인 IP(Intelligent Peripheral)에 대하여 IP의 성능을 평가하기 위한 성능 조건을 제시한다. IP의 성능을 구성하는 서비스 기준, 신뢰도 및 가용도, 시스템 트래픽 처리용량의 3가지 요소에 대하여 필요한 세부항목들을 제시하고 목표치를 설정한다. 이러한 항목 및 목표치들은 IP의 구조 및 운용환경 등이 확정되면 추후 수정보완도리 예정이다.

PSTN에서의 과금은 해당 서비스에 대한 착신 지역 및 사용 시간(period)과 서비스 시간대에 국한된 것이었고, N-ISDN에서는 패킷 처리에 따른 데이타량이 추가되었다. 광대역 종합 통신망에서는 ATM Traffic이 가지는 다양한 서비스들의 특성에 맞게 요금을 산정하기 위해 과금 방식의 유연성, 과금 처리의 신속성과 정확성이 요구된다. 과금은 교환기 자원의 이용에 대한 use rate를 부가하는 것으로 초기 망구축 시에는 ATM Mind확장을 위해 망 운용자의 정책적인 결정에 의해 부가될 것이며, 그 이후 서비스에 대한 반대급부와 서비스 원가주의에 의해 결정될 것이다. 본 논문에서는 광대역 종합 통신망에서 권고된 프로토콜 중 과금에 관련된 요소를 제시한다.

The purpose of this study is to find out what the contribution of medical service design to improve the quality of medical service has contributed to the resolution of medical authority, and to draw the implications necessary to further develop the medical service industry. As a method of research, first, the concept of medical authority was considered and the internal and external factors of medical authority were examined. Second, by examining the cases of medical service design, which resolved the medical emphasis inherent in internal and external factors, the key points and significance of problem solving were analyzed based on the core results. Third, the implications were to form a patient-centered medical culture for respect and dignity for patients, to break up the conventions inside medical staff to dismantle medical authority, and to establish a fair communication system for sharing medical information.

National industrial complexes, airports, and seaports are major logistics nodes and the availability of their logistics services is a key factor for the successful operation of entire supply chains. For this reason, the central government has established a plan for their development and is investing in development projects. However, some difficulties exist in project prioritization and investment plan creation owing to the absence of a clear appraising method. For a smooth flow of national logistics and efficient investment on facilities, it is necessary to diagnose the logistics facilities' present conditions and practice sustainable management. In this study, a diagnostic method for logistics services, which consists of service factors and facility factors, is proposed. Adopting the method, facility factors can be prioritized to improve facilities' services; further, a standard procedure is proposed to support decision making for effective investments in logistics facilities. The method is applied to actual logistics facilities (three national industrial complexes, three seaports, and two airports) and the results indicate that it can be effectively applied to actual logistics facilities.

In order to provide customized services according to a specific user or environment, various service scenarios should be developed based on context-aware workflow model. As the context-aware workflow model is constructed using limited context information and service information in the service domain, overlapping elements can occur in many service scenarios. The repetitive work process that results from these overlapping elements delays the development process of the service scenario. Therefore, the elements of the context-aware workflow model must be reused to solve the unnecessary work processes of service scenario development. In this paper, we propose a reuse method XML Object in context-aware workflow model to improve the process of service scenario development. The proposed method documents and manages the independent XML Object of the context-aware workflow model and reuses it by invoking the unit document in the service scenario development process. It can also be applied to new service scenarios by changing the attribute values of reusable elements. Experiments show example that the development process of the service scenario is simplified by reusing the elements of the context-aware workflow model.

Recently, as interest in social robots to support physical convenience and emotional sympathy has increased, and social internet has developed, a social robot has evolved as various services simply beyond robot function. Therefore, to develop a social robot service effectively, it is required to study the functional application and methods of interaction between user and social robot service. The purpose of this study is to classify social robot services and to suggest the types of elements that need to be considered in service development. To do this, we conducted in-depth case studies and analysis based on the theoretical definitions and characteristics of social robots. Then, based on the sympathy and functions, we classified social robot services into 1) emotional support type, 2) companion type, 3) guide type, and 4) life support type. In addition, in this study, we derive the considerable factors according to the classified types for the development of effective social robot services. This study will contribute to the understanding and development of various services using a social robot.

This research was tried for developing the model on the service science research scope. The suggested model is composed as 3 layer dimensional reference model. The first axis is on the perspective of service life cycle. Another second axis is on the service research characteristics or types. And last axis is also on the service systems. At here, service life cycle is related to service strategy, service development, and service implementation of operation. The service research characteristics or types is related to service basic research, service application research, and service convergence research. Lastly, the service systems is related to the needs analysis, service competence and service resources. This model can be applicable to include the various research topic or theme related on the service sciences. In the future, some enhanced models from researchers or practices from service providers, related on the service science research scope, are expected.

본 논문의 목적은 모바일 서비스를 위해 GML 프로파일을 개발하는 것이다. 현재 모바일 서비스를 위하여 다양한 형태의 지도 표현과 공간정보 서비스가 개발되고 있다. 그러나, 각 모바일 서비스마다 표준화되지 않은 독자적인 방법을 통해 공간 데이터를 전송 및 처리하고 있어서 모바일 서비스간의 상호운용성을 확보하기 어려운 상황이다. 이를 해결하기 위하여 GML을 기반으로 모바일 서비스용 GML 프로파일을 개발한다. 모바일 서비스 환경을 위한 실용적인 GML 프로파일을 개발하기 위해서는 GML 명세와 모바일 서비스를 먼저 분석하여야 한다 GML의 구성요소와 모바일 서비스 및 DB분석을 기반으로 MATRIX분석을 수행하여 모바일 서비스를 위해 필요한 GML 구성요소의 부분집합을 정의한다. 이를 기반으로 모바일 서비스용 GML 프로파일을 개발한다.
